From a survey of 100 college students, a marketing research company found that 50 students owned iPhones, 45 owned cars, and 35 owned both cars and iPhones.
40 owned neither
To determine the number of college students who owned either a car or an iPhone, we need to calculate the total number of students who owned a car or an iPhone and subtract the number of students who owned both.
Number of students who owned a car = 45
Number of students who owned an iPhone = 50
Number of students who owned both a car and an iPhone = 35
To calculate the number of students who owned either a car or an iPhone, we can add the number of students who owned a car and the number of students who owned an iPhone, and then subtract the number of students who owned both.
Number of students who owned either a car or an iPhone = (Number of students who owned a car) + (Number of students who owned an iPhone) - (Number of students who owned both)
= 45 + 50 - 35
= 95 - 35
= 60
Therefore, from the survey of 100 college students, 60 students owned either a car or an iPhone.
